Smith\nChief, Safety Utilities Division\nArizona Corporation Commission\n1200 W. Washington Street\nPhoenix, AZ 85007\nDear Mr. Smith:\nThis responds to your letter of August 22, 1995, about marking plastic valves. You asked us to\nreconsider our interpretation of May 1, 1995, that 49 CFR 192.63(a) does not require plastic valves to be\nindividually marked. We further said that plastic valves are acceptably marked if packaged together until\nuse, with the required marking on the package. This interpretation was first stated in a letter dated\nAugust 5, 1994, to Massoud Tahamtani of the Virginia State Corporation Commission.\nYou suggested that if plastic valves are manufactured to ANSI B16.40, they must be marked according\nto ANSI B16.40. This code specifies certain markings, and provides that two of the markings must be\npermanently affixed to, or incorporated as part of, the valve. The other markings may be affixed by any\nmeans.\nWe still believe you are viewing §192.53(a) too rigidly. The rule requires plastic valves to be marked\neither as prescribed in the specification or standard to which they were manufactured or to indicate\ncertain other information. Because the rule permits valves to be marked with information other than what\nthe standard of manufacture specifies, without dictating the method of marking, any marking method that\nsatisfies the purpose of the rule is sufficient for compliance. As we said previously, the purpose of\n§192.63(a) is to require that the identity of pipeline materials be shown from the time of manufacture to\nthe time of use. This purpose is met by proper package marking as long as the material remains in the\npackage until use.\nSincerely,\nRichard D. Huriaux, P.E.\nDirector for Technology and\nRegulations\nOffice of Pipeline Safety\n95-10-20.doc 192.63","truncated":false,"body_characters":1972}
